Hellhound

Hellhounds, sometimes simply called "dogs," are dog like creatures that run and bite players, similar to the K9 Unit in Multiplayer. Unlike Multiplayer, these dogs are a lot bigger and on fire. Hellhounds deal less damage than zombies. It takes three hits from a Hellhound to down a person. They only appear on every five rounds or so on select maps. They do not walk into a room like zombies - instead they teleport into the map. Once all Hellhounds are defeated, a Max Ammo will appear from the last hound.
